サンバーストチャートの作成

サンバーストチャートを使用して、階層データを表示できます。このグラフでは、個々の階層レベルは1つのリング（円）として表現されます。最も内側の円が、階層の最上位のデータです。

次の図は、複数のリングから成るデータを示します。

サンバーストチャートを追加するには、SunburstSeriesおよびSunburstPlotAreaクラスを使用します。

チャートデザイナを使用したチャートの作成については、「チャートデザイナ」を参照してください。

設定方法

シートにデータを設定します。
シートのAddChartメソッドを使用して、1.のデータを参照するチャートを追加します。

サンプルコード
